Blade reinforcement composites

There are two primary reinforcement composite materials used today: fiberglass and carbon fiber. Fiberglass is a high-performance economical composite suitable for many turbine blade designs. As blade designs become longer, and blade weight more critical, carbon fiber reinforcements are typically used. Lighter blades help reduce the overall nacelle weight and therefore the rotor structural support needed.

We have expertise in both consulting with blade designers to determine the best composite based on turbine specification, as well as in the manufacturing of the fiberglass and carbon fiber reinforcements.

We are happy to consult with you on the best composite solution to fit for your design.

Our composite solutions for wind turbines include:

Blade reinforcements and rotor blade laminates

Spar caps

Turbine blade root joints, fiberglass spacers and carrots

Cable management systems

Service platform structures and ladders

Generator insulation solutions

Why pultrusion is important for the wind energy

A combination of design and manufacturing expertise provide our foundation for pultrusion manufacturing.

We understand how to use carbon fiber in the most cost efficient manner to meet cost, weight, and strength requirements, and our pultrusion manufacturing expertise is a key to efficient carbon fiber use.

Pultrusion is a continual process that reduces production waste and time and maintains a consistent production quality compared to other composite manufacturing processes.

With the pultrusion process, composite fibers are first impregnated with a thermoset resin and then are pulled through a heated die where the resin cures. Additional laminate overlays are possible, as well as the addition of reinforcement mats, fabrics and multiaxial products.
